General introduction


1. General introduction

This manual does not cover all aspects and functions of the DRS system. However it covers all essential procedures and aspects for a safe operation and maintenance of DRS-COMPACT2A and DRS-LIGHT numerical protection relays. For explanations operation software DRS-WIN is used preferably.

1.1. Application

The digital protection system DRS is a multifunctional protective relay to supervise and protect synchronous as well as non-synchronous machinery, transformers and the combination of generator/transformer units, motors and power supply feeders. All for a complete protection scheme required components, e.g. input CT/VT circuits, measuring circuits, trip logic and alarm output matrix, auxiliary supply, keypad operation and local display, are available in one device.

1.2. Operation

The incoming signals from the protected plant, e.g. CT current, VT voltage and binary inputs, are transferred via the denominated terminal connections to the protective device. The computation of these signals with the exception of hardware interference suppression is fully digital. The advantages of digital evaluation are the utmost immunity of the system against component aging, temperature, etc. as well as the possibility to even carry out complex protective duties with a relative simple computable algorithm. Thus the characteristic values of the incoming CT and/or VT signals can be made available for several different protective functions. The implemented protective functions in the relay are evaluated sequentially 12 times per cycle. Depending on the operating mode of the protected plant, i.e. normal service operation or fault conditions, the protective device produces the corresponding alarm and/or trip commands. These signals are distributed via a software matrix according to the configured tripping scheme. Optical LED displays indicate the instantaneous alarm annunciation and/or the trip of a protective function. Via a PC further detailed data about the fault sequence such as the fault and event records can be saved, displayed and processed. Configuration and parameter settings are stored into a non-volatile EEPROM. Each change of the parameter settings can be displayed in a modification protocol and printed for further use.

Operating instructions


2. Operating instructions

2.1. Operation using software DRS-WIN

2.1.1. Connecting to the relay

In order to set up an online connection between a DRS-COMPACT2A relay and a PC plug in the interface cable GID-030

1 or TID-006

2 into the interface situated at the front of the relay and to the PC. For a DRS-LIGHT use

the interface GID-0143. Start the software DRS-WIN.

DRS-WIN searches for connected devices automatically right after the start. If the search fails or does not start, choose the item Communication Ports in menu Communication. Every detected serial interface port is displayed. Choose the one which is used for the connection to the DRS and click OK. An automatically started search on the enabled ports for the devices takes place. Such a search can be started manually at any time also by clicking on menu item Search for connected devices in menu Communication.

The parameter file stored in the protection relay is downloaded to the PC. A window appears showing the implemented functions as shown in the figure below. DRS-WIN main application window DRS device window Area for DRS windows

2.1.2. Device window

All the activated protective functions and the indication of the connection status can be seen in the device window. The most important measured values and the settings of the device are accessible via the icons in the toolbar of the device window. Change trip matrix Change LED matrix Show operating measured values Print all DRS data Send all data to DRS Safe all data to file Read all data from DRS

Chain address Event protocol Disturbance recorder

Fig. 3 Device window in DRS-WIN

To display the settings of a protective function click on the function name. A new window appears where the setting values of the chosen function are displayed and can be changed. To display the settings for the trip matrix click on the matrix icon. A new window appears where the trip matrix is displayed and can be modified. The file name is created automatically on saving the data to a file on a storage media. Each relay has a unique identification and the file extension VE. In this file all the settings are stored. The default folder for storing VE files can be opened by pressing key F11 or clicking on View Plant Files in menu View. A VE file is required for the initialization of a DRS spare unit. A password must be entered before a modification of the parameters is possible. Please refer to section 2.1.7.



2.1.3. Modified data and the reference file

With the very first downloading of the parameters from a protection relay the DRS-WIN creates automatically a reference file. This file contains all settings of the protective functions of a DRS. In case of changes of settings of protective functions the DRS-WIN compares the new settings with the data in the reference file. A warning triangle on the bottom of the device window indicates that there is a difference between the setting file and the reference file. To accept the differences in comparison to the reference file, click on the warning triangle and a dialog window opens like in figure below. Which kind of parameter was changed is displayed in this window in a tree view. It is possible to accept the changes with the button Save reference file and the warning triangle disappears in the device window.

Fig. 4 Modified data in comparison to reference file



2.1.4. Binary input/output preset

The binary input/output preset can be used to activate the binary inputs and outputs of the protection relay for testing. The state of the binary inputs or outputs can be set in this window. It is also possible to monitor the actual state of the inputs and outputs. Activating in menu System the menu item Binary I/O Preset opens the window for binary value preset.

Fig. 5 Binary I/O preset in DRS-WIN

By clicking on current state of an input or output a window opens where the required state of the input or output can be set with button Apply or OK until Regular function is selected and Apply or OK is pressed again. The difference between these two buttons is that with OK the window is closed whereby with Apply the window remains open.

Fig. 6 Forcing binary inputs and outputs with DRS-WIN

In case the window of the Binary I/O Preset is closed all the inputs and outputs are set to Regular function automatically.



2.1.5. Disturbance recorder

In case a fault was recorded or in case disturbance records are stored in the DRS device the symbol of an oscillogram appears on the bottom of the device window. The number in the area beside the symbol of the oscillogram indicates how many records are stored in the DRS device. Click on the oscillogram symbol to open the window for reading the disturbance records. A dialog window opens like in the following figure.

Fig. 7 Reading disturbance records from device with DRS-WIN

Select a fault record and press the button Read Disturbance Record. Now the fault recording is downloaded from the DRS device to the PC which can take some time. It is possible to cancel the downloading without losing the downloaded data. Press the disc symbol in the window of the fault recording to save a read disturbance record.

Fig. 8 Disturbance record window in DRS-WIN



The file name is created automatically. The default folder for storing disturbance records can be opened by pressing key F8 or clicking on View Dist. Records in menu View. Three files are stored for each disturbance record.

They have the extensions CFG, DAT and HDR. Just the CFG and DAT files are required to open the disturbance record with a COMTRADE viewer. The HDR file contains additional data of the device and the view for DRS-WIN.

2.1.6. Event recording

All alarms and trips are stored in the event protocol. The records can be stored in a file by pressing the disc icon. The default folder for storing event recordings can be opened by pressing key F9 or choosing View Event Protocols in menu View. The file names for the event recordings are created automatically by the DRS-WIN and contain the relay denomination and the time when the event record was stored.

Fig. 9 Event protocol view in DRS-WIN

2.1.7. Password input

For each modification of the parameters the DRS-WIN requires a password. This is to avoid that the parameters are changed unintentionally. The password is individually selectable for each DRS and is stored in the DRS file and in the device. The password can be changed via the menu System on menu bar. The default password is ‘A’.

Fig. 10 Entering password in DRS-WIN



2.1.8. Fault status

In case of an internal relay failure details can be found in the menu System, DRS Fault Status.

Fig. 11 Fault status display in DRS-WIN



2.2. Operation using local display and keypad

The user interface of a DRS relay consists of a two-line LCD with 16 characters each line and a keypad with 6 keys. During normal operation, e.g. after start up or expiring of the corresponding timeouts, the device is in the main menu, i.e. the display light is off and the first line of the display indicates the version of the device and the hardware version. The second line displays the currently measured operating values of the various CT and VT inputs as well as additional function measured values which are selected by the user. When a monitoring routine detects a fault, the display light is switched on and the display shows !!DRS FAULT!! in the first line. The display light stays on until the fault condition is reset manually. Then the kind of relay fault can be viewed in the submenu Display Fault Status (section 2.2.4). If the relay operates, the last alarm or trip (plant specific denomination or protective function name) is indicated on the display. The function with the last alarm or trip is only shown on the display when at least one of the alarm or trip LED is on. All alarms and trips with additional information as time and stage of alarm or trip can be viewed in the submenu Output Event Protocol (section 2.2.2). The local operation is designed in a way that all relay parameters can be displayed without password input. But modification of any setting parameters can only be carried out by entering the correct password.



Following buttons and keys are available:

Reset button blue

Serves to reset the optical indication (status LED, alarm and trip LED) as well as for LED test.

Membrane keypad

6 keys for local operation of the relay. Entries are menu controlled corresponding to the indication shown on the relay display.

Following keys are available in the menu Display Fault Status: ▲ ▼ scrolls through the faults (if present).

◄ ► scrolls through the inputs or outputs in case of a binary input or output fault.


EXIT returns to the main menu.

2.2.5. Password Input

Default password: A All actions when working with the relay which lead to modification of the existing configuration are protected with a password. Without entering the password the parameter settings can only be viewed but not changed. To enter the password following request is shown on the display:

Enter Password * A

Now the displayed character can be modified via the ▲ ▼ keys to the first character of the password. If necessary a new character can be entered by moving the cursor with the ► key to the next right positioned digit and can again be modified to the next password character with the ▲ ▼ keys, and so on. If a character is entered incorrectly it can be deleted with the UNDO key or corrected with the ▲ ▼ keys after setting the cursor with the ◄ ► keys on the wrong character. After selecting the last password character the procedure is terminated with the OK key. When the correct password is entered any further operations are authorized.



Otherwise following display is shown:

Wrong Password! * B

In this case the entry has to be repeated or corrected as outlined before.



2.3. LED indications

Of the 28 LED (DRS-COMPACT2A) / 10 LED (DRS-LIGHT) at the relay front 2 of them are allocated to the system status indication (green/red in the 1

st row) whereas the remaining LED serve as instantaneous and time delayed

trip displays. The LED denominations respectively their allocations to the protective functions are shown on the designation label beside the LED.

Status LED (row 1)

LED in service (green) (O)

Steady light Normal service operation

Voltage supplies are present and within limits.

Flashing light The relay is in service, but no protective functions are active either being not

configured or in an operating mode where no protective functions are carried out,

e.g. a spare relay not initialized.

Dark No supply voltage and not ready for service. This condition will be registered by the

relay’s fault alarm contact.

LED fault (red) (F)

Dark No system fault and normal service conditions

Flashing light The self monitoring system has detected a category 1 failure. For troubleshooting

please refer to section 3.2.

Steady light The self monitoring system has detected a category 2 failure. For troubleshooting

please refer to section 3.2.

Alarm and trip LED (row 2 to row 14) Indication of instantaneous and/or time delayed trips are provided by the freely programmable yellow alarm and red trip LED allocated to the various protective functions in row 2 to row 14 (DRS-COMPACT2A) / row 2 to row 5 (DRS-LIGHT). The LED are configured to be hand reset.

2.3.1. Resetting of LED indications

Prior to resetting the LED indication the cause for this, especially for the status LED display, should be investigated and rectified if necessary.

Reset of instantaneous and delayed trip LED

The alarm and/or trip LED can be reset by shortly pressing the blue reset button located above the LED row. During this process all LED will be illuminated for test purposes. Resetting the indication has in no way any influence on fault and event records.

Reset of the status LED

By resetting the status LED all other indications are reset also, but not any analog fault and none of the event records stored in the device.

Maintenance instructions


3. Maintenance instructions

3.1. Maintenance and inspection plan

The DRS relays are maintenance free relays with no user serviceable parts. During the life of the relay it should be checked for operation during regular maintenance period of protected primary equipment (e.g. generator, transformer). ANDRITZ HYDRO GmbH as manufacturer of DRS series of protective relays recommends a maintenance interval of 4 to 6 years. The work to be done for DRS relay maintenance includes consistency check of parameter file (refer chapter 2.1.3), secondary injection including pick-up values and trip characteristic, alarms to SCADA system, trip outputs, measured values and binary inputs. It is recommended that the following tests are carried out:

3.2. Malfunction

The DRS protection relays are provided with extensive self monitoring and self checking systems which produce a corresponding optical indication (local display – section 2.2.4; LED – section 2.3) and operate a status relay. A DRS-COMPACT2A is equipped with two normally closed contacts (BO.31/32). A DRS-LIGHT has one changeover contact.

NOTICE

Each fault alarm indicates that the system is not fully functioning and the user has to make the decision whether or not the protected apparatus should remain in service.

3.2.1. Procedure in case of malfunction

Determine the type of failure on the local device (section 2.2.4) or by usage of the software DRS-WIN (section 2.1.8) and write it down. Use the form given in section 6. If there are entries in the event protocol and saved disturbance records which occurred in the period around the relay failure please save them too, see sections 2.1.5 and 2.1.6. Two categories of faults are distinguished by status LED (please refer 2.3): Category 1: Perform a reset of the status LED according to section 2.3.1. Category 2: Perform a hardware reset. A hardware reset can be performed either by disconnecting

the power supply or by DRS-COMPACT2A: pressing Reset button at the relay. DRS-LIGHT: pressing the keys SHIFT + ESC + UNDO for approximately 3 seconds.

NOTICE

A hardware reset shall be only performed during standstill.

Pressing the keys SHIFT + ESC + UNDO for approximately 3 seconds at a DRS-COMPACT2A relay resets the communication processor unit responsible for the communication to the control system. This can be performed if the failure message is related to any SIP or NIP error. The execution of the protective functions is not affected by a reset of the communication processor unit. On the next pages instructions are given.

NOTICE

Switching off the power supply erases all internal records (disturbance records, event records, and DRS fault status).



3.2.2. Troubleshooting DRS-COMPACT2A

Two categories of faults are distinguished: Category 1: without blocking of the protective functions. Only status contact BO.31 is in origin position. Category 2: with blocking of the protective functions. Status contact BO.31 and BO.32 are in origin position. Section 3.2.3.1 and 3.2.3.2 list these faults.

3.2.4. Universal interface module UAKB used for rotor earth fault protection

The rotor earth fault protection applies a DC voltage between the excitation circuit and earth for measuring the rotor earth resistance.

Fig. 13 Rotor earth fault protection: signal injection

CAUTION

The relay is injecting ±50 V between field and earth!

Depending on the plant configuration the wire can be automatically disconnected by a contact (e.g. field breaker, field flashing). In such case an alarm is suppressed via interlocking with the circuit breaker position or via connecting a capacitance to ground. Please check the circuit diagram.

3.2.4.1. Measurement transducer UAKB supervision

The rotor earth fault protection can detect if measuring circuit is interrupted. In this case the rotor earth fault protection can be blocked (according parameterization of software function) and a corresponding alarm is initiated.

3.3. Repair of malfunctions

3.3.1. Exchange of relays

If a relay is not working properly it has to be exchanged.

WARNING

The following steps have to be met as minimum requirement:

Disconnect completely

Secure against re-connecting

Verify that the installation is dead (de-energized).

Carry out grounding and short-circuiting

Provide protection against adjacent live parts

WARNING

Current transformer circuits need to be short circuited first before the wiring connected to the relay can be removed. A current transformer produces a very high voltage if the current transformer circuit is open-circuited with the primary energized. This can damage the electrical equipment and can harm the operation staff.

NOTICE

Working at the protection system shall only be performed when the protected object is out of service.



3.3.2. Initialization of a spare unit

In case a DRS is configured as a spare unit, the following display indication appears after switching on the relay power supply:

SPARE Vx.xx/xx SETUP REQUIRED!!

In addition the green LED in the first row is blinking. Should the device not be in the status of a spare unit, please refer to section 2.2.3.3. The DRS spare unit has to be programmed with a parameter file. Parameter files have the file extension VE. The user interface of the respective DRS spare unit has to be connected via the operation cable to the PC (RS232 interface for DRS-COMPACT2A, RS485 interface for DRS-LIGHT). After starting the DRS-WIN software a connection to a spare unit is detected automatically. Refer to section 2.1.1 if no spare unit is automatically detected.

Fig. 15 Initializing a spare unit: initial prompt

By confirmation of starting the initialization with OK, the user is asked to select the required parameter file. A correct selection has to be ensured and completed by pressing the button Open. The Browse feature provides the access to the folder with the files if the VE files should not be stored in the default folder Plants,

Fig. 16 Initializing a spare unit: selection of the required VE file



For safety reasons a reconfirmation is implemented for the file selection:

Fig. 17 Initializing a spare unit: confirmation

DRS-Win starts automatically loading the data of the file into the DRS.

Fig. 18 Initializing a spare unit: loading

The device is ready for operation which is indicated by an Online connection status.

Fig. 19 Initializing a spare unit: relay ready for operation

It is recommended to do a short check of the device status:

Check actual relay measuring values

Check status of binary relay inputs and outputs

Check trips of protection functions with software test inputs (Binary I/O Preset, section 2.1.4)



3.3.3. Universal interface module UAKB

The UAKB unit is an optional module of the DRS COMPACT2A and provides an extension of the functionality. The type code defines if the relay is equipped with an UAKB module. Certain functionalities of the UAKB module need calibration or parameterization (rotor earth fault protection, stator earth fault protection, shaft current protection, PT100 evaluation). To avoid doing this in case of a relay exchange, it is recommended to install the UAKB of the relay to be replaced in the new relay. If key H is 4, 5 or 6 in product code, the relay is equipped with an UAKB module
